Introducing the 2003-2007 Dodge Ram 5.9L Cummins silicone air intake hose kit from Mishimoto! This replacement for the factory Cummins turbo air duct replaces your overly-restrictive corrugated plastic hose with a smooth, free-flowing silicone tube that improves airflow and durability. The Mishimoto intake tube eliminates the ribbed stock piping, reducing turbulence into the turbo and increasing efficiency. We've also removed the muffler that's integrated into the stock pipe to further improve flow and add some induction noise to your Cummins.----. The Dodge Ram 5.9L Cummins silicone air intake hose is constructed from five layers of silicone with embedded stainless-steel wire to provide improved durability and resistance to collapsing with high flow. This intake hose is available in black, blue, and red and features includes worm gear clamps for easy installation. As with all Mishimoto products, the 2003-2007 Dodge Ram 5.9L Cummins silicone air intake hose kit is backed by our Mishimoto Lifetime Warranty.
